.Modelica_LinearSystems2.StateSpace.Import.fromFile

Information

Syntax

ss = StateSpace.Import.fromFile(fileName, matrixName)

Description

Reads and loads a state space system from a mat-file fileName. The file must contain the matrix [A, B; C, D] named matrixName and the integer nx representing the order of the system, i.e. the number of rows of the square matrix A.

Example

algorithm
  ss:=Modelica_LinearSystems2.StateSpace.Import.fromFile("stateSpace.mat", "ABCD");
//  ss=StateSpace(
      A=[-1, 0, 0; 0, -2, 0; 0, 0, -3],
      B=[1; 1; 0],
      C=[1, 1, 1],
      D=[0])

Interface

encapsulated function fromFile
  import Modelica;

  input String matrixName = "ABCD" "Name of the state space system matrix (default is \"ABCD\") in the fileName" annotation(
    Dialog);
  output StateSpace result(redeclare Real A[nx, nx], redeclare Real B[nx, nu], redeclare Real C[ny, nx], redeclare Real D[ny, nu]) "State space description of model read from file";
